Abstract

Using Cauchy's equation the complex potential of a two-dimensional non-linear wave is solved in the presence of submerged bodies at various depths and of various shapes. Two types of submerged resonant duct are considered, one open mouthed and the other incorporating a reflector, and crosssections of a wave lens used for focusing waves into a central area by effectively changing the depth of water through which the waves propagate. The solution is then time stepped until the wave breaks, and the resulting forces and moments on the bodies are calculated.
